Mean, Median, Mode, Range Calculator

A simple, focused tool to calculate the four most common measures of central tendency and dispersion (Mean, Median, Mode, and Range) for any set of numbers.

⏳

Formula

Mean = Sum / Count | Range = Maximum - Minimum
Mode
The most frequently occurring number(s)
Median
The middle value when sorted (or average of two middle values)

Example

Finding Measures of Central Tendency

Calculate for the data set: 4, 1, 7, 1, 2.

  1. Sort the data: 1, 1, 2, 4, 7.
  2. Mean: (1+1+2+4+7)/5 = 15/5 = 3.
  3. Median: The middle value in the sorted list is 2.
  4. Mode: The number 1 appears twice (most frequent).
  5. Range: Maximum (7) - Minimum (1) = 6.
  6. Result: Mean=3, Median=2, Mode=1, Range=6.

Frequently Asked Questions

Yes. If multiple numbers tie for the highest frequency, the dataset is called 'multimodal' and all of those numbers are considered modes. If no number repeats, the dataset has no mode.
